THOMAS J. '.LINDALL, OF NEIV YORK, N. Y.'

wAsHrNe-MACHINE.

To all whom it may concern:

Be it known that I, THOMAS JEFFERSON TINDALL, of the city, county, and State of New York, have invented certain new and useful Improvements in the Apparatus for Washing Clothes and other Articles; and I do hereby declare that the following is a reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is an elevation of the apparatus; and Fig. 2, a vertical section thereof.

The same letters indicate like parts in both figures.

In my said invention the clothes or other articles to be washed, are put in a vertical vessel with heated water or suds or other suitably prepared liquid, and the top closed air tight, and th'en by means of a pump or equivalent means connected with the upper part of the vessel the air and then the vapor is exhausted from the upper part of the vessel which will remove the pressure from the surface of the heated water or other liquid which will in consequence be thrown into violent ebullition although at a less temperature than 212 degrees of Fahrenheits scale.

In the accompanying` drawings ci reprew sents a` vessel which maybe of any suitablI form, that represented in the drawings being the one which I have tried with success and prefer. It is provided with trunnion journals b fitted to turn in suitable boxes in the standards of a frame c so that it can be turned in the position represented by dotted lines for convenience in emptying out the contents. And when the vessel is to be charged it is held in the vertical position represented by a spring CZ attached to the frame. This vessel, which I prefer to make and with a rounded edge c, and adapted to receive a cap f which has a ilanch g with an annular groove in its under face packed with vulcanized india rubber or other equivalent elastic substance, which, when the cap is put on the vessel, bears on the rounded edge c, so that when the said vessel is exhausted the pressure ofthe atmosphere on the outer sur face of the cap shall force the packing onto the rounded edge e and thus make and maintain an air tight joint.

To the side of the vessel is attached the cylinder h of a single acting air pump, which by a suit-able passage z' communicates with the upper part of the vessel a. The rod y' of the piston of the air pump is connected with a hand lever /c which works on one of the trunnion journals Z9 as a fulcrum, so as not to interfere with the turning of the vessel ct on its trunnion ournals.

The clot-hes or other articles to be washed are charged in the vessel a and the heated water or other liquid poured in, and the cap f put on and pressed down with the hand, if not sufficiently heavy, until it is firmly held down by the pressure of the atmosphere. The air pump is then. operated which exhausts the air and vapor from the upper part of the vessel. The liquid in the vessel is thus relieved of pressure and will in consequence be thrown into violent ebullition, and as the clothes are also relieved from the pressure, the ebullition of the liquid will throw them up and loosen them thereby facilitating the passage of the liquid through them, so that in a very short time the dirt will all be washed out without subjecting them to that kind of violent friction which is so injurious in washing machines.

When the clothes have been sutliciently washed the cap is removed and the vessel turned down in the position represented in dotted lines to empty out the contents.

Any other exhausting apparatus may be substituted for the air pump, as the only purpose of the pump is to exhaust the upper part of the vessel.

The vessel may be made of any other suitable form and may be mounted in any other manner, and if desired the cap may be secured and packed in any other suitable manner which will admit of exhausting the vessel.

I am aware that prior to my invention a pump has been used in connection with a vessel containing the clot-hes to be washed and the washing liquid, but in such case the pump was made to communicate with the vessel both above and below the charge o1" clothes, the pump exhausting the air and liquid from the vessel below the charge of clot-hes and forcing it into the vessel above the charge, thereby compacting the charge of clothes and obstructing instead of facilitating the circulation of the washing liquid through the clothes; and besides, in such cases, the circulation of the washing liquid was effected by the actionof the pump instead of its ebullition caused by simply ren ducing the pressure above as in my method.

What I claim as my invention in the before described apparatus for Washing clothes and other articles, is-

Colnbining with a suitable vessel for containing the clothes &c. to be Washed and the Washing liquid, an exhausting pump or equivalent therefor, communicating` With the said vessel above the intended charge, substantially as described, to exhaust the said vessel above the charge and relieve the Vpressure to effect the circulation of the Wash- 10 ing liquid by ebullition below the recognized boiling point, as set forth.
